Hi Kevin:<br>
>S: Secondly, I believe that B&L ? prove? (pp. 15, 19, 186-198) that MJ provides only about ? half? the incentives? >or opportunities for anti-democratic ?strategic? voting to be successful. If you disagree, please explain the flaw in their argument.<br>
<br>
K: What I understood from Kristofer's Jan 4 explanation of page 15 is that?this halving of the manipulability is not meant to be a comparison to?any other methods. It's a comparison to a (rather strange) hypothetical situation. If so, this claim on its own
could be true but is of unclear value.<br>
Possibly this argument is used to build up to a larger argument. But when it gets stated on its own it feels misleading to me, because there's no way for the reader to understand what this "half" is half of.</font></span></p>

“half” of the incentives and opportunities to “manipulate” the results as compared to all the methods that gain their results by “summing” or “averaging” all the votes.<span style="mso-spacerun: yes;">
</span>In his reply to me, Kristofer also gave me a link to the following source in which B&L concisely state the same claim on slide 150.<span style="mso-spacerun: yes;">
</span>This is in the middle of their discussion of “strategy”, i.e. between slides 143 & 185:</font></span></p>
